Har Apple TV en intern volymkontroll? Ljudet i TV är mycket lågt.
ChatGPT sade:
Apple TV (oavsett modell, HD eller 4K) har ingen egen volymkontroll för ljudutgången. Den skickar alltid ut ljudet i full nivå (”line level”) till TV:n eller förstärkaren.
Det betyder att du inte kan höja eller sänka volymen i Apple TV:n själv. Volymkontrollen sker i stället:
Via TV:ns fjärrkontroll (om du använder TV:ns högtalare).
Via förstärkaren/ljudanläggningen (om du har kopplat Apple TV via t.ex. HDMI ARC eller optisk ljudingång).
Via Siri Remote – men då styr den egentligen TV:ns eller förstärkarens volym, inte Apple TV:ns. (Den gör detta med hjälp av HDMI-CEC eller IR-signal.)
👉 Om ljudet i din TV är mycket lågt när du kör Apple TV kan det bero på:
Att TV:ns egna ljudinställningar är lågt satta (kontrollera ”digital ljudutgång” eller ”HDMI-ljudnivå”).
Att förstärkaren/ljudanläggningen inte är på rätt volymnivå.
Att Apple TV är inställd på ett ljudformat som TV:n hanterar sämre (kolla i Inställningar > Video och ljud > Ljudformat och prova att stänga av ”Ändra format” eller byta mellan Dolby Digital 5.1 och Stereo).
Vill du att jag går igenom steg-för-steg hur du kan felsöka varför ljudet är så lågt på just din setup?
Du sade:
Jag har en Beovision 7 som är integrerad med Beomaster 7000. Ljudet kommer genom ett par Penta-högtalare från Bang & Olufsen
ChatGPT sade:
Aha, då förstår jag! 🙂
Du kör alltså Apple TV → BeoVision 7 → Beomaster 7000 → Penta-högtalarna.
I den kedjan är det inte Apple TV som styr volymen (som sagt, den har ingen intern volymkontroll), utan det är BeoVision 7 som reglerar ljudnivån och skickar det vidare till Beomaster 7000/Pentorna via PowerLink.
Om ljudet upplevs väldigt lågt vid just Apple TV-användning finns några saker att kolla:
🔧 Felsökning
Ljudformat på Apple TV
Gå till Inställningar > Video och ljud > Ljudformat.
Prova att stänga av “Ändra format” så att Apple TV skickar ut Dolby Digital eller PCM stereo direkt.
Om du redan har det avstängt, prova att slå på och välj “Stereo”. Många äldre B&O-system hanterar ren stereo bättre än Dolby Digital.
Ljudinställningar i BeoVision 7
Kolla under Options > Sound. Där finns inställningar för “Speaker”, “Sound Mode” och “Loudness”.
Se till att Speaker 2 eller 5 är valt (beroende på om fler högtalare är inkopplade).
Kontrollera att inte AV-nivån för extern källa (Apple TV:n är ju inkopplad via HDMI/DVI) är nedskruvad. BeoVision tillåter olika ljudnivåtrim för olika källor.
Integration med Beomaster 7000
Eftersom du har länkning till Beomastern: kontrollera att du inte har dubbel volymkontroll (BeoVision på låg nivå och Beomaster som inte kompenserar).
Vanligen bör BeoVision stå som ljudmaster när den används som bildkälla.
👉 Fråga till dig: Är ljudet lågt bara på Apple TV eller även på andra källor (DVD, TV-tuner etc.) via BeoVision 7?
Det avgör om vi ska justera Apple TV-inställningarna eller BeoVisionens interna källnivåer.

Now the radio is acting up: when I turn it on, it is set to volume 14. When I increase the volume, it skips straight o volume 32, buzzes for three seconds, and then goes back to 14
ChatGPT sade:
That sounds like a control or communication fault between your Beomaster 7000 and the rest of the system – not just a normal “option setting.”
On the Beomaster 7000, volume is digitally stepped (not analog), so what you describe:
Starts at 14 (that’s the default “power-on” level if no last volume is stored).
When you raise the volume, it jumps straight to 32 instead of stepping smoothly.
Then it buzzes for a few seconds (could be the muting relay or the power amp going unstable).
Finally it resets back to 14.
This strongly suggests one of the following:
🔧 Possible causes
Faulty volume control IC / microprocessor glitch
The Beomaster 7000 uses a digital volume control chip. If it misreads the commands (from Beo4/Beolink or the front panel), it can jump to wrong levels.
EEPROM or memory issue
Normally the Beomaster “remembers” the last used volume. If memory fails, it may revert to a default (14).
Communication issue with Beovision 7
If the Beomaster is link-controlled by the TV, they might be “fighting” over the volume setting. One device pushes it to 32, the other resets it to 14.
Power supply ripple / capacitor aging
A buzzing sound for 2–3 seconds often comes from tired capacitors or relays not engaging cleanly.
✅ What you can try (non-invasive)
Disconnect the Beovision 7 and run the Beomaster 7000 standalone with your Penta speakers. See if the volume behaviour changes.
Do an Option reset on the Beomaster:
Put Beomaster in standby.
On Beo4, press Standby + List until OPTION appears.
Press GO, then select Option 1 (standalone audio system).
If it still always goes back to 14 → the issue is inside the Beomaster.
💡 Since you’ve already been struggling with odd behaviours in the setup (no sound in one room, option programming quirks, now this volume bug), it could point to the Beomaster 7000 itself needing service (recapping, relay check, or volume IC replacement).
Do you want me to walk you through a simple test so you can see if the Beovision is forcing the Beomaster back to volume 14 — or if it’s really an internal Beomaster defect?
Du sade:
Please!
ChatGPT sade:
Perfect 👍 let’s do this step by step — this will tell us whether the Beovision 7 is “forcing” the Beomaster’s volume back down, or if the Beomaster itself is misbehaving.
🔎 Test procedure
Disconnect the Beovision 7 completely
Unplug the BeoLink/PowerLink cables that connect Beovision 7 to the Beomaster 7000.
Leave only the Penta speakers connected directly to the Beomaster.
Power up the Beomaster on its own (no TV).
Power on the Beomaster 7000 (standalone)
Put it into Option 1 (standalone audio master):
On Beo4, press Standby + List until OPTION appears.
Press GO, then 1.
Now turn on RADIO.
Test the volume control
See what the Beomaster displays at startup (14 is common if it can’t recall memory).
Try raising volume step by step with the Beo4.
Note if it behaves normally (smooth 15, 16, 17… etc.) or if it still jumps to 32, buzzes, and falls back to 14.
📊 Interpreting the result
If the problem is gone (smooth stepping):
→ The Beovision was sending back conflicting volume commands. We can then adjust the option programming so they don’t “fight.”
If the problem remains (still jumps and buzzes):
→ The Beomaster 7000 itself has a hardware fault (volume IC, control logic, or power supply). Then we’re looking at service/repair.
👉 Would you like me to also give you the instructions for setting Beovision 7 and Beomaster 7000 in the correct option mode if it turns out to be a “control fight”?
Du sade:
It went directly to volyme 36 when I tried to increase from 14, and then returned to 14. No buzz. I only connected on of the Pentas
ChatGPT sade:
Great — that’s actually a very useful test result. Thanks for running it.
What we’ve learned:
The buzzing came from the TV/Beovision link being in the chain — with the Beovision disconnected, that symptom is gone.
But the jumping volume (14 → 36 → back to 14) is still there, even with just one Penta directly on the Beomaster.
👉 That means the problem is inside the Beomaster 7000 itself, not the Beovision.
What this points to
The Beomaster 7000 volume control isn’t an analog potentiometer, but a digitally stepped IC controlled by the microprocessor. What you describe (overshooting to 36, then “snapping back” to 14) is classic of one of these issues:
Volume IC or logic fault
The IC (or the CPU commanding it) doesn’t increment step by step, but misfires to a “default max value,” then the processor corrects back to the startup level.
Memory / EEPROM problem
The Beomaster normally remembers the last volume. If it can’t write or read properly, it may always fall back to 14.
Aging capacitors or PSU instability
If the control voltage rails are noisy, the digital volume can behave erratically.
What you can still try (non-invasive)
Front panel controls: If you press the physical ▲/▼ volume buttons on the Beomaster (not the Beo4), does it behave the same way?
If both remote and front panel give the same jump → it’s the internal volume logic.
If only one works badly → it could be the remote command interpretation.
Option reset (again): Set Beomaster to Option 1 after disconnecting power for a few minutes. Sometimes clears a “stuck” logic state.
Test with the other Penta: Just in case the single speaker’s PowerLink cable is introducing noise (unlikely, but worth ruling out).
If fault persists
Then you’re most likely looking at a hardware repair of the Beomaster:
Replacement/repair of the digital volume control chip or processor interface.
Service check of the power supply capacitors (common on 7000-series now, they’re aging).
⚡ Question for you:
When you use the front panel volume buttons on the Beomaster (instead of the Beo4), does the volume still jump straight from 14 → 36 → back to 14?
Du sade:
There are no front panel volume buttons on the Beomaster 7000. At least I can’t find any
ChatGPT sade:
You’re absolutely right 👍 — unlike older Beomasters, the Beomaster 7000 has no physical volume knob or buttons on the unit itself. All control is done by remote (Beolink 1000, Beo4, or Beolink 7000). Thanks for catching me there.
So: the fact that you only control volume by IR remote means the “jump to 36 → reset to 14” behaviour is definitely inside the Beomaster’s logic/volume circuit and not just a sticky button.
What this means in practice
The Beomaster boots with default volume 14 (fails to recall last level).
Any attempt to change volume causes the control logic to misinterpret the command, overshoot to 36, then the processor “snaps” it back to default 14.
That’s consistent with either:
Faulty digital volume IC (common issue as these chips age).
EEPROM/memory fault (not storing last state, always resetting).
Power supply instability (control voltages to the logic circuit aren’t clean).
Next safe step you can try
Since we can’t bypass the remote control system:
Power cycle fully
Disconnect the Beomaster 7000 from mains for at least 5–10 minutes.
Reconnect and try again.
Sometimes clears a “logic loop” if it’s software/EEPROM related.
Test with a different remote
If you have access to a Beolink 1000 or another Beo4, try.
It’s rare, but if your Beo4 is misfiring IR codes, it could be sending “jump” commands instead of step-by-step.
Isolate further
Run the Beomaster with nothing but one Penta (no datalink, no Beovision, no other sources connected).
Try RADIO → adjust volume.
If it still always does 14 → 36 → 14, then we’re down to internal service.
Typically a recap + volume IC check/replacement is the cure (the IC is a digitally controlled attenuator, and when unstable, it causes exactly this kind of behaviour).
👉 Do you want me to check whether there are still B&O specialists in Sweden (near Malmö) who can service Beomaster 7000 — or would you prefer I walk you through DIY-style checks (like measuring PSU rails, looking for bad caps) if you’re comfortable opening it?
Du sade:
I already tried disconnecting everything except one Penta, used Beolink 7000 to increase the volume, after leaving e Beomaster disconnected for five minutes. Same result. Hi-Ho Music in Makmö has serviced this Beomaster before. The authorised specialists are way to expensive. Maybe there is someone in Denmark…
ChatGPT sade:
Great—thanks for running those thorough checks and confirming the problem persists internally. Since you’re open to service options beyond the local (expensive) authorized specialists, here are some promising routes—especially in Denmark—that could be more affordable yet still reliable:
Repair Options in Denmark
MasterPlay (EU-based service)
This service offers refurbished CPU boards specifically for the Beomaster 7000, which could address memory/logic issues that reset volume to default (14) or cause erratic jumps. For €80–€150 (depending on the extent), they offer:
CPU board replacement — €80
Full service — around €150
masterplay.eu
This seems like a solid mid-priced option, especially if the issue is on the logic side rather than full power supply failure.
Local Danish Technician — via BeoWorld forum
On the BeoWorld forum, someone mentions contacting a service workshop in Denmark specifically for the Beomaster 7000:
“I have now contacted a service workshop here in Denmark, I am very excited about what it will cost”
forum.beoworld.org
This indicates that there are existing, possibly independent technicians in Denmark familiar with vintage B&O servicing—perhaps less costly than the officially authorized ones.
Another anecdote from a user in Denmark:
“My Beomaster worked again… I can only guess it was some bad soldering and it fixed itself on the way to the service.”
archivedforum.beoworld.org
It’s a good sign that a more affordable technician managed to fix a similar issue (possibly with reflow or recapping), sometimes without charging for diagnostics.
Spare Parts Retailers
If you’re comfortable exploring DIY or partially servicing it yourself (or with local technician help), DK Sound Parts is a Danish supplier specializing in vintage B&O spare parts. They stock a range of components for Beomaster 7000, from microcomputer boards to transformers and preamp PCB:

Du sade:
Masterplay: We are closed for summer and open again in the beginning of september.
We wish our B&O friends a nice summer and welcome back.
your MasterPlay.EU staff
ChatGPT sade:
Got it 👍 — so MasterPlay themselves confirm they’re closed until early September. That explains why we couldn’t reach a contact address just now.
That leaves you with three practical paths in the meantime:
Wait until September and then contact MasterPlay directly for their CPU board service/repair (likely the best fix if the problem is in the Beomaster’s logic board).
Look for a Danish workshop or independent tech who handles Beomaster 7000s. Since you’re close to Denmark, that might be faster/cheaper than waiting or paying Swedish authorized B&O rates.
Source parts (e.g. CPU board, PSU caps) in advance from places like Kose Trading in Copenhagen, so you’re ready if you decide to repair locally or DIY.
👉 Do you want me to track down specific independent repairers in Denmark (with addresses/contacts), so you’d have an alternative to waiting for MasterPlay?
